how to increase efficiency of coal boilers

efficiency coal fired boiler - athen-viersen.de

How to Run a Coal Fired Boiler at the Best Efficiency . Boiler efficiency is mainly depended on the amount of losses in the system. In high capacity pulverized coal fired boilers the total losses account to about 12 to 14%. Roughly 50% of the losses are governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions.
